I've been trying out some new keyboards recently, I laid my hands on K70 MK.2 with MX Brown switches as well. What kinda surprised me is that the software for K70 does not include an option I used a lot in other keyboards, which is opening a specific folder.

Logitech or HyperX keyboards have that option included in software, but it's nowhere to find in iCUE. I actually have tons of folders I need fast access to, and these software shortcuts assigned with folder opening where very handy to me.
